Halfway Between 51 and 331

When you ask "What number is halfway between 51 and 331?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=51 and Y=331.

Halfway Between Line

To find the number halfway between 51 and 331, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 51 and 331 into our formula, we get:

(51 + 331)/2 = 191

Thus, the number halfway between 51 and 331 is 191.

To check that our answer is correct, we subtract 51 from 191 and subtract 191 from 331 and compare the two numbers:

191 - 51 = 140
331 - 191 = 140

As you can see, the halfway number is 140 higher than 51 and 140 lower than 331. Therefore, our halfway between answer of 191 above is correct.
